Small and flexible binoculars with an incredibly clear and high-contrast image. The lenses feature a GPObright™ lens treatment: Each lens is multi-coated on both sides for a light transmission of up to 99.7% per lens. In an optical system, the sum of the light losses of all lenses and prisms is crucial for the overall light transmission. An untreated quality glass can lose up to 5% of the light per lens (reflecting it away).
